FEMALE TREES

 

Parthenocarpic Female Fig 單性結實期 - the development of a fruit without prior fertilization

Pollinated Female Fig 授粉階段 - a seed fertilized by pollens

 Pollinated and Parthenocarpic fruits of Ficus septica 棱果榕


 

THE TWO RIPENING CHARACTERISTICS OF MALE FRUITS:

1- Parthenocarpic characteristic
2- Pollinated characteristic

MALE FRUITS
of
Ficus septica

1- Pre-receptive Stage

Ficus septica is a Dioecious雌雄異株 tree that male figs and female figs are grown on seperate trees. While a Monoecious 雌雄同株 tree have both male galls and female seeds within every single fig fruit. For example Ficus benjamina is a Monoecious tree.

 

 


2- Wasp-receptive Stage

The above image is a laying egg Female fig wasp few moment ago was freshly emerged from another ripened male fig from the same tree. It has successfully entered this young male fruit through the ostiole.

Male pollinators never never visit another young fig after emerging because they have no more mission in another young fig. They have completed their mission after fertiling other new female and duck a hole out at the ostiole for the females wasps to escape to lay egges in a new young figs in another fig tree (either male tree or female tree)

The above is a non-pollinator (a non fig wasp) laying eggs from outside a male fig using long tube inserting.

Female parasitic wasps do not lay eggs in female figs because female figs do not have galls for incubating eggs.

MALE TREE
 

Ficus septica Burm.f. is a small free-standing tree distributed from the Solomon Islands and Northern Australia,
throughout insular South East Asia, to Taiwan and the Ryukyu Islands. It belongs to subgenus Sycomorus, section
Sycocarpus and it is functionally dioecious (functionally male trees bear figs that produce pollinating wasp offspring and pollen but no seeds, while female trees bear figs that produce seeds but neither wasp offspring nor pollen)
